Which of the following molecules is most abundant in the cells of the human body?

• Nucleotides
• Water
• Lipids
• Amino acids

Unlike other animals, mammals can perspire. The main benefit of perspiring is that it —

• removes dirt from the surface of the skin
• cools the skin with evaporation
• relaxes the muscles
• removes extra water from the cells

A microorganism which releases water into its environment to regulate its salinity during osmosis is undergoing a process that is similar to a human being who releases moisture on a hot day. This process that helps keep both the microorganism and the human body fluids in balance is known as —

• heredity
• homeostasis
• mutation
• cell division
